我有一张包含超过10万个六位数CIP代码和相关标题的表格：
SixDigitCIPTable：
SixDigitCIPCode | SixDigitCIPTitle
========================
01.0000 | Agriculture, General
01.0102 | Agribusiness/Agricultural Business Operations
01.0201 | Agricultural Mechanization, General
03.0501 | Forestry, General
05.0112 | South Asian Studies
我需要用两位数和四位数的CIP代码和标题来映射它。 四位数的CIP表就像，
FourDigitCIPTable：
FourDigitCIPCode FourDigitCIPTitle
=====================================
01.00 | Agriculture, General
01.01 | Agricultural Business and Management
01.02 | Agricultural Mechanization
03.05 | Forestry
05.01 | Area Studies
TwoDigitCIPTable：
TwoDigitCIPCode | TwoDigitCIPTitle
===================================
01 | Agriculture, Agriculture Operations, And Related Sciences
01 | Agriculture, Agriculture Operations, And Related Sciences
01 | Agriculture, Agriculture Operations, And Related Sciences
03 | Natural Resources And Conservation
05 | Area, Ethnic, Cultural, Gender, And Group Studies
我已经在三个不同的SQL表中加载了每个两位，四位和六位CIP查找值。 我需要在SixDigitCIPTable中插入两位数和四位CIP细节以及相应的值。
例如，
SixDigitCIPTable的第一条记录是，
01.0000 | Agriculture, General
所以两位数代码将为01，同时将这两位数字代码映射到TwoDigitCIPTable中，记录到地图是，
01 | Agriculture, Agriculture Operations, And Related Sciences
和四位数代码将是01.00，同时将这个四位数代码映射到FourDigitCIPTable中的记录到地图是，
01.00 | Agriculture, General
所以在SixDigitCIPTable中插入两位和四位数代码后，第一条记录应该是，
01 | Agriculture, Agriculture Operations, And Related Sciences | 01.00 | Agriculture, General | 01.0000 | Agriculture, General
最后SixDigitCIPTable应该是，
TwoDigitCIPCode | TwoDigitCIPTitle | FourDigitCIPCode | FourDigitCIPTitle | SixDigitCIPCode | SixDigitCIPTitle
=======================================================================
01 | Agriculture, Agriculture Operations, And Related Sciences | 01.00 | Agriculture, General | 01.0000 | Agriculture, General
01 | Agriculture, Agriculture Operations, And Related Sciences | 01.01 | Agricultural Business and Management |
01.0102 | Agribusiness/Agricultural Business Operations
01 | Agriculture, Agriculture Operations, And Related Sciences | 01.02
| Agricultural Mechanization | 01.0201 | Agricultural Mechanization, General
03 | Natural Resources And Conservation | 03.05 | Forestry 3.0501 | Forestry, General
05 | Area, Ethnic, Cultural, Gender, And Group Studies | 05.01 | Area Studies |05.0112 | South Asian Studies
在SQL中是否有可能这样做？
